>>That 150 pound class minimum weight is a scaled down all carbon A class boat that costs $15,000.00 US Dollars. What these posts are talking about is a $1500 dollar boat finished and ready to go racing
Try tortured 3 mm and 4 mm marine ply. Gets you easily to 160 lbs on a 14 footer and costs less than a glass boat as well (lets alone carbon). There will be no 1500 US boats as sails mast and block will cost more than that.
Let we not forget that torture ply boats of low weight are already build by many sailors. Think paper tiger, arrow and sorts.
Besides Carbon is not more expensive than glass; major cost is the labour anyway.
